When I get a little money I buy books; and if any is left I buy food and clothes. —Erasmus

In our field, things change so fast, the most up to date resources are usually online, but there are also some must-read books out there that are really worth checking out.

Over the years, I’ve put together a decent collection of books on web analytics, digital marketing, and related topics. There are a number of blog posts out there with different reading lists and favorites. This is not “the” list, it’s my canon - the books in my permanent collection that have been very useful in various related areas. YMMV.

I have not read every word in all of them. Some I have read cover to cover, and more than once. Some I just use for reference and quick lookups. You might think some of these aren’t essential for a career in digital analytics or digital marketing and you’re probably right. But these are some of my favorites, and anyone starting out in this field would defintely benefit from reading any of them.

If one of your favorites is missing, either I don’t own it, or I haven’t read it, or I forgot to include it. Please let me know if there’s something you think is a “must read”, I’d love an excuse to place more orders at Amazon.

I was at the ACCELERATE conference in Atlanta yesterday, the classy Web analytics conference run by the (rapidly growing) Web Analytics Demystified team. The presenters and content were top-shelf across the board, as you would expect from such a talented and experienced group. Josh West, Partner at Demystified and Adobe Analytics expert extraordinaire dropped this bomb during Q&A:

More mobile devices are activated each day than there are babies being born.

Huh? Say again? What the? I don’t think I heard anything else for the next 10 or 15 minutes as my brain tried to get some kind of handle on this data-point grenade. How many mobile devices is that, really?

“In the first decade of the 21st century, the number of people connected to the internet worldwide increased from 350 million to more than 2 billion. In the same period, the number of mobile-phone subscribers rose from 750 million to well over 5 billion (it is now [2013] over 6 billion).”1

UNICEF estimates that an average of 353,000 babies are born each day around the world. The CIA World Factbook puts the number at 367,576. Even if we round way up, and say 375,000, just the number of Android devices activated each day is 1,500,000.2

So, at least 4 times the number of babies being born - JUST for Android devices. Whoa.

There are (roughly) 7.2 billion people on the planet. That number includes lots of little ones in diapers. OK, yes, some older ones in diapers too. Let’s just call them outliers or non cell phone users. In May of this year, the International Telecommunication Union estimated3 there were nearly 7 billion mobile subscriptions worldwide. “This is equivalent to 95.5 percent of the world population.”

“Ericsson have forecast that global mobile internet subscriptions will reach 4.5 billion by the end of 2018, with the mobile phone remaining the most frequently used access device”.4 So more than half the planet will have mobile internet subscriptions? The Web in their pocket. We’re gonna need more cat pictures.

Mary Meeker points out there’s still A LOT of upside potential in smartphone growth as a percentage of total mobile subscribers, as only about 30% of mobile is smartphones today, but as smartphones continue to get cheaper, that accelerating growth rate should continue to follow the steep growth trend of the recent past.

These numbers are freaking me out a bit. How much traffic is running over the tubes through all these pocket computers? Cisco5 says that in 2013, global mobile data traffic grew more than 81 percent, year over year, to 1.5 exabytes per month.

Exabytes? I work on the Web all day long and I can’t guess how many bits and bytes that is. Apparently, that’s the storage capacity of 250 million DVDs. Two hundred and fifty million DVDs worth of cat pictures, animated GIFs, Snapchats, Insta-flickr-book-face photos, Vines, and who knows what else going through CELL PHONES. Every month. Really?

If Kevin Kelly6 is right (again) and “the internet is still at the beginning of its beginning”, we still have some time to work out all of those mobile strategies we keep hearing we need to fix, and pivot, and execute. Numbers like these make me think “mobile first” should really think long and hard about the “mobile only” generation, which appears to be coming up in the rearview really freakin fast. Like a multi-exabyte tidal wave. Better clench up, Legolas.
